DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic substance processing apparatus for processing organic substances such as garbage.

[0002]

2. Description of the Related Art At present, in households and convenience stores where organic substances such as garbage are discharged, an organic substance processing apparatus is often used for the purpose of self-processing the organic substances.

As shown in FIG. 25, for example, such an organic substance processing apparatus has a processing tank 200 in which a carrier for microorganisms is placed, into which organic substances are charged and stirred by a stirrer 201 to decompose organic substances by the microorganisms. To be processed.

At this time, in order to activate the microorganisms and accelerate the decomposition of organic substances, the processing tank 200 is kept at, for example, 60 ° C.

[0005] Since an odorous gas is generated during the decomposition treatment of organic substances, if the exhaust gas is exhausted as it is, it gives a user uncomfortable feeling.

Therefore, the gas to be exhausted is heated to about 250 ° C. to 300 ° C. by the heater 202 and is brought into contact with the catalyst 203 to perform oxidative decomposition.

As described above, the exhaust gas is heated to increase the deodorizing efficiency, and most of the heat is released to the outside air. On the other hand, the processing tank 200 needs to be heated in order to promote the decomposition treatment of organic substances.

Therefore, the exhaust gas is led to the bottom 204 of the processing tank 200, where the processing tank 200 is heated so that the heat can be effectively used.

The organic matter decomposed in the processing tank 200 becomes a powdery processed material, which is mixed with the exhaust gas and flows into the catalyst, causing the catalyst to be clogged.
A filter (not shown) is provided to remove the powder.

[0010]

However, since the filter requires maintenance such as regular cleaning and replacement, there are the following problems.

That is, if the maintenance of the filter is forgotten, the filter is clogged and the exhaust gas is difficult to be exhausted, and the air volume of the outside air supplied to the processing tank 200 due to the exhaust is reduced, so that the efficiency of the organic matter decomposition treatment is reduced. Will drop.

Also, if the filter is washed and the like, and the user forgets to remount the filter, or if the filter is inadvertently removed during operation of the apparatus, powder enters the catalyst 203 and the like, and the catalyst becomes It may cause clogging.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a highly reliable organic substance processing apparatus which prevents such a filter from being forgotten for maintenance or reattachment, and is prevented from being taken out carelessly.

[0014]

Means for Solving the Problems To solve the above problems, the invention according to claim 1 is a processing tank accommodated in a main body case for processing organic substances, and an openable and closable input for charging organic substances into the processing tank. In an organic material processing apparatus having a lid and a filter for removing powder contained in exhaust gas from the processing tank, a filter insertion port is provided in a main body case at a lower portion of the loading lid, and when the loading lid is opened. Only the filter is detachable.

According to a second aspect of the present invention, the charging lid is formed by a double lid of an outer lid and an inner lid, and a recess is formed in the inner lid so that the inner lid does not abut on the handle of the filter. It is characterized by the following.

In the invention according to claim 3, the side plate of the inner lid is
It extends to the rear side plate so as to surround the depression formed in the inner lid, and reinforces the strength reduction due to the formation of the depression in the inner lid.

In addition,
The arrows shown in FIGS. 2 and 3 indicate the flows of the outside air and the exhaust gas.

The organic substance processing apparatus is used for business purposes, for example, in a convenience store or the like. The organic substance processing apparatus is provided with a processing section 2 which decomposes organic substances put in a processing tank 9 while stirring them with a stirrer 10. A driving unit 3 for supplying power, a ventilation unit 4 for circulating outside air to the processing tank 9 and exhausting gas generated in the processing tank 9 outside the machine, a deodorizing unit 5 for deodorizing a gas exhausted outside the machine, organic matter The main components are a discharge unit 6 for taking out the processed material obtained by the decomposition treatment outside the machine, a charging unit 7 for charging the organic matter into the processing tank 9, and alarm means (not shown) for monitoring the state of the apparatus. Are stored in the main body case 8.

The processing section 2 has a processing tank 9 in which a carrier of microorganisms (usually wood chips such as sawdust) is stored in advance and an organic substance to be decomposed is charged. And a discharge plate 12 having a smaller capacity than the partition plate 14, and a stirring body 1 for stirring organic matter in the processing tank 9.

FIG. 5 is a perspective view showing the structure of the frame 13 for accommodating the processing tank 9, and FIG. 6 is a view showing the structure of the processing tank 9.

The processing tank 9 is divided by a partition plate 14 into a processing chamber 11 and a discharge chamber 12. Organic substances such as garbage are put into the processing chamber 11 to perform a decomposition process. The processed material which has been decomposed in the processing chamber 11 and turned into powder is transferred to the discharge chamber 12 by the movement of the stirrer 10, and is waiting to be discharged outside the machine in the discharge chamber 12. .

The transfer of the processed material from the processing chamber 11 to the discharge chamber 12 is performed via a transfer port 15 provided at the upper end of the partition plate 14, and a transfer door is provided at the discharge chamber 12 side of the transfer port 15. 16 are provided.

The transfer door 16 is formed so as to be larger than the transfer port 15 and has an upper end rotatably attached to the partition plate 14 so that the processed material in the discharge chamber 12 is not transferred back to the processing chamber 11. Has become.

The processing tank 9 has a substantially U-shaped side section and a double bottom structure at the bottom, and a plurality of air distribution plates 18 are arranged in a row in the double bottom space 17. I have.

The exhaust gas heated in the deodorizing section 5 passes through the double-bottomed space 17 and is exhausted to the outside of the machine. At that time, the processing tank 9 is heated by the exhaust gas. .

At this time, if the exhaust gas blows against a part of the processing tank 9 and the processing tank 9 has a large temperature distribution, the processing object may be scorched, especially when stirring is stopped.
Microorganisms in high temperature parts may be killed.

Therefore, a dividing plate 18 is provided in the double bottom space 17.
Is provided. The air distribution plate 18 is a plate material arranged so as to block the exhaust gas. When the exhaust gas hits the air distribution plate 18, the exhaust gas is dispersed right and left to the entire double bottom space 17. I am going to cross.

Although the exhaust gas is dispersed by the air distribution plate 18 throughout the double bottom space 17, the applied heat is quickly diffused and spread to reduce the temperature distribution of the processing tank 9. As shown in FIG. 6, a heat equalizing member 20 is provided on a bottom surface 19 of the processing tank 9 having a double bottom.

The heat equalizing member 20 is made of a material having a high thermal conductivity (eg, aluminum, copper, nickel, zinc, etc.), and is provided on the bottom surface 19 of the processing tank 9 by sticking or plating. I have.

If the heat equalizing member 20 is provided so as to be pressed against the processing tank 9 by the air distribution plate 18, the separation of the heat equalizing member 20 and the adhesion between the heat equalizing member 20 and the processing tank 9 are improved. It is effective on.

Further, the raw garbage just put into the processing tank 9 contains a large amount of water, so that it comes into close contact with the inner wall of the processing tank 9 and a part of the raw garbage remains even when the stirring body 10 is driven. May be.

Generally, when newly adding garbage,
In the treatment tank 9, in addition to the microorganism carrier described above, there is a treated product that has been decomposed. Therefore, these are mixed with the raw garbage that has been input.

For this reason, when the garbage is stagnated as described above, the garbage which is stagnated is reduced even if the temperature distribution of the processing tank 9 is not large or the temperature is low. Since the heating is always performed, the temperature may increase, causing burns or death of microorganisms.

In order to prevent such a state, it is preferable to coat the inner wall of the processing tank 9 with a heat-resistant and slippery stagnation prevention member 21 such as a fluororesin.

The stirrer 10 has a rotating shaft 22 rotatably supported, a number of stirring rods 23 provided at a phase shifted from the rotating shaft 22, and the like, and is supported by a bearing member described later. Have been.

Further, the side plates 28a and 28b of the processing tank 9 are formed with a diameter that is appropriately larger than the rotation shaft 22 and are provided with through holes 35 through which the rotation shaft 22 is inserted. A screw hole 36 for fixing is provided.

Further, a bearing unit 31 and a bearing support bracket 32 are provided on the side plates 28a and 28b of the processing tank 9.
The insertion hole 37 through which the screw 112 that engages with is inserted. The insertion hole 37 is formed to be appropriately larger than the diameter of the screw 112, so that the positioning of the bearing member 30 can be adjusted as described later.

When the agitator 10 is mounted, the left and right bearing units 31 and the bearing support 3
2 is temporarily aligned with the position of the through hole 35, and the rotating shaft 22 is inserted. Thereafter, the sprocket 25 is fixed and the position of the rotating shaft 22 is adjusted.

After the position of the rotating shaft 22 has been adjusted,
At least one of the bearing unit 31 and the bearing support fitting 32 can be welded 113 to the side plates 28a and 28b.

As described above, by providing the bearing support bracket 32, the seal fixing plate 34, and the like in the processing tank 9, the following effects, which cannot be obtained conventionally, can be achieved. FIG. 10 shows a conventional configuration corresponding to FIG.

By protruding the bearing support fittings 32 and the like into the processing tank 9, the processing tank 9 can be enlarged by the amount of the protrusion without increasing the external dimensions of the organic material processing apparatus. Processing capacity can be increased.

Further, since the bearing support bracket 32 and the like are provided so as to protrude into the processing tank 9, the distance between the sprocket 25 and the corresponding side plate 28a is shortened, and
2 is reduced. Therefore, the force for holding the bearing unit 31 can be reduced with a small force.
b can be reduced in thickness.

Further, unlike the conventional case, the bearing plates 32a and 28b are not fixed to the side plates 28a and 28b by welding. Since the position of the unit 31 can be maintained, there is no displacement of the rotating shaft 22 caused by the misalignment of the welding position of the bearing support bracket 32, and the left and right bearing units 31 can be easily aligned to simplify the assembly work. Will be able to

The charging section 7 is provided on the upper surface of the main body case 8 and is used for charging the organic matter into the processing tank 9. The charging section 38 is provided in the periphery of the charging lid 38 when the charging lid 38 is closed. A packing 39 and the like are provided to prevent outside air from entering the apparatus from the charging lid 38 by being in close contact with the main body case 8.

FIG. 11A shows the state when the input lid 38 is opened.
FIG. 11B is a diagram showing a state when the charging lid 38 is closed.

The input lid 38 is a heat insulating lid formed of an inner lid 40 and an outer lid 41, and is provided with a hinge 42 at the rear end side so as to be open to one side with respect to the main body case 8 and at the front end side. Is provided with a handle 43, which lifts the handle 43 to open the input cover 38.

FIG. 12A is a perspective view of the outer lid 41, and FIG.
(B) shows the sectional view. FIG. 12 (c)
Is a perspective view of the inner lid 40, and FIG. 12D is a sectional view thereof.

A depression 44 is provided on the hinge 42 side of the inner lid 40 so that a filter handle 59 described later does not abut. Note that the packing 39 is provided so as not to include the depression 44.

As can be seen from the figure, since the recess 44 is formed by bending the plate material forming the inner lid 40 into a concave shape, there is a concern that the strength of the loading lid 38 may be reduced. Therefore,
The left and right side plates 40a, 40b of the inner lid 40 are extended to the rear side plate 40c so as to surround the recess 44, thereby preventing such a decrease in strength.

FIG. 13 is a detailed view of the input lid 38 centering on the hinge 42. A magnet 45 is provided near a handle 59 of the filter, and a first lid 40 is provided on the inner lid 40 at a position facing the magnet 45. A switch 46 is provided, and a second switch 47 is provided on the body case 8 side. These operations will be described later.

The discharge section 6 is provided on the front side of the apparatus, and has a discharge port 49 provided by opening the lower part of the discharge chamber 12 in the processing tank 9 and the main body case 8. Is composed of a chute 51 that slides down the swash plate 50 and is discharged outside the machine, a discharge door 53 that opens and closes a discharge port 49 by a handle 52, a door cover 54 that covers the discharge door 53 and the handle 52, and the like. .

FIG. 14A is a top view of the discharge section 6 and FIG.
(B) shows a front view thereof, and FIG. 15 shows a side view of the discharge section 6. At this time, the door cover 54 is not shown in FIG. 14B, and a handle position regulating rib 64 and a key 62 described later when the door cover 54 is closed are indicated by dotted lines. FIG. 16A is a perspective view of the chute 51, and FIG. 16B is a perspective view of the door cover 54.

The discharge door 53 has a handle 52 and a discharge door lock 55. A handle 56 is provided at one end of the handle 52, and a roller 57 is provided at the other end. Further, the discharge door lock 55 is of a screw type, and when tightened, the tip of the screw hits the discharge door 53 so that the discharge door 53 does not move.

Then, with the discharge door lock 55 loosened, the handle 52 is rotated (the handle 56 is pushed down).
Then, the roller 57 of the handle 52 is guided by the guide member 58 fixed to the discharge door 53, and the guide member 5
8, the discharge door 53 is moved upward, and the discharge port 49 is opened.

On the other hand, when the discharge door 53 is closed, the operation is reversed. When the discharge door 53 is to be kept closed, the discharge door lock 55 is tightened.

At this time, the opening of the discharge chamber 12 and the opening of the main body case 8 are connected by a chute 51 having a swash plate 50 inclined downward so that the processing object can be smoothly taken out.

If only the swash plate 50 is used as the chute 51, there is a problem that the processed material spills down from the left and right end portions of the swash plate 50, and the processing tank 9 and the main body case 8 are not in close contact with each other and there is a gap. However, there is a disadvantage that outside air enters the apparatus from the gap and cools the processing tank 9 and the like.

In order to cope with such inconvenience, side plates 50a, 50b and 50c are provided on the swash plate 50 as shown in FIG. 16 so that the gap between the processing tank 9 and the main body case 8 is closed.

The discharge door 53 and the handle 52 are covered with a door cover 54. The door cover 54 is provided with a key 62 to prevent the handle 52 from being operated carelessly. I have.

As shown in FIG. 16, the door cover 54 is a one-sided double door and is a hinge side plate 54a and an upper side plate 5a.
4b is fixed to the main body case 8, and the hinge-side side plate 54a
The side plate 54c and the lower side plate 54d facing the
And the front plate 60 is opened and closed.

An overhanging plate 61 is provided on the upper side plate 54b, and a key 62 is engaged with the overhanging plate 61. The key 62 has an engagement piece 63, and the engagement piece 6
Locking is performed by rotating 3 to be positioned on the back surface of the overhanging plate 61.

A handle position regulating rib 64 for regulating the position of the handle 52 is provided on the back surface of the front plate 60 of the door cover 54.

FIG. 17 shows such a handle position regulating rib 6.
FIG. 17A is a diagram illustrating an example of a failure that occurs when the door cover 54 is closed when the cover 4 is not provided. FIG.
(B) is a front view. In FIG. 17B, the door cover 54 is omitted and illustrated as in the case of FIG. 14B. However, the position of the handle position restricting rib 64 is illustrated by a dotted line, and the handle position restricting rib 64 is illustrated. The positional relationship between the handle 64 and the handle 52 is clearly shown.

As described above, FIG. 17 corresponds to FIG. 14, and the operation of the handle position restricting rib 64 can be easily understood by comparing these drawings.

Normally, after the processed material is discharged from the processing tank 9, the discharge door 53 is closed, but sometimes the discharge door 53 is forgotten to be closed.

However, in the case where the handle position restricting rib 64 shown in FIG. 17 is not provided, the door cover 54 is closed even if the discharge door 53 is not closed. When the apparatus is operated as it is, the processed material is discharged from the processing tank 9 and is blocked by the door cover 54.

If the door cover 54 is opened without knowing that this is the case, a large amount of processed material will spill outside the machine, and the heat of the outside air will be directly transferred to the processing tank via the door cover 54. 9 to cool the processing tank 9 and reduce the processing efficiency.

Therefore, a handle position regulating rib 64 is provided so that when the discharge door 53 is not closed,
The door cover 54 is not
, The handle position restricting rib 64 hits the handle 52 so as not to close.

Since the open / closed state of the door cover 54 can be checked from the outside, the open / closed state of the discharge door 53 can be easily known, and the above-mentioned inconvenience can be prevented.

When the handle position restricting rib 64 is not provided, even if the discharge door 53 is closed, the discharge door lock 5
If the user forgets to close 5, vibration or the like is transmitted to the device from the outside for some reason, and it is assumed that the handle 52 moves.
In such a case, the state is substantially the same as when the discharge door 53 is forgotten to be closed.

However, by providing the handle position restricting rib 64, even if the handle 52 attempts to move due to external vibration or the like, this movement is controlled by the handle position restricting rib 64.
Is regulated, so that such inconvenience can be prevented.

Since the door cover 54 covers the discharge door 53, the door cover is substantially a double door, and the heat of the outside air is not directly transmitted to the processing tank 9. Therefore, it is possible to prevent a reduction in processing efficiency due to the provision of the discharge door 53.

The deodorizing section 5 includes a heater 65 for heating the gas to be exhausted, a deodorizer 66 disposed downstream of the heater 65 for deodorizing the gas heated by the heater 65, and a heater 65. And a storage box 67 for storing the deodorizer 66 and a storage lid 68 as a lid thereof.

FIG. 18 is an exploded perspective view of the deodorizing section 5, FIG. 19 is a top view of the deodorizing section 5, and FIG.

The heater 65 is formed by forming a plurality of ventilation holes 70 in a rectangular parallelepiped 69 made of quartz or ceramic, and passing a nichrome wire 71 therein.
7.

The deodorizer 66 is provided with a catalyst 73. The catalyst 73 is a cylindrical one having a honeycomb-shaped fine ventilation hole 74 formed therein, and is stored in a storage box 67 via a heat insulating material 75. ing.

Then, the exhaust gas from the processing tank 9 is supplied to the heater 65 through the filter, and the exhaust gas heated by the heater 65 is supplied to the deodorizer 66 to be deodorized.

At this time, since the exhaust gas is heated by the heater 65, the temperature of the exhaust gas supplied to the deodorizer 66 is high, thereby promoting the decomposition reaction of the exhaust gas by the catalyst 73. As a result, the deodorizing efficiency is improved.

The storage box 67 has the storage lid 6 as described above.
The storage lid 68 is provided with a storage lid closing prevention cover 76 and a one-touch lock 77 for engaging the storage lid 68 with the storage box 67.

The one-touch lock 77 is fixed to the storage lid 68, and is provided with a hook 78. The one-touch lock 77 is fixed to the storage box 67 and a lever 80 urged by a spring 79.
To prevent the storage lid closing prevention cover 76 from closing even when the lever 80 is closed in a state where the hook 78 and the engaging claw 81 are not normally engaged. It has a prevention member 82 and the like.

As a result, the lever 80 is opened (the lever 8
0), the hook 78 is engaged with the engaging claw 81, and the lever 80 is closed (the lever 80 is laid down) to fix the storage lid 68 to the storage box 67.

Conventionally, the storage lid 68 was screwed to the storage box 67, so that maintenance work was troublesome. However, with the above configuration, the storage lid 68 can be opened and closed with a single touch, thus improving workability.

FIG. 21 is a view for explaining the operation of the non-engagement prevention member 82 when locking the storage lid 68. FIG. 21 (a) shows a case where the non-engagement prevention member 82 is not provided. FIG. 21B shows a state in which the lever 80 is closed in a state where the hook 78 and the engaging claw 81 are not engaged when the non-engagement preventing member 82 is provided. In the figure, the dotted line indicates the storage lid closing prevention cover 76.
FIG. 21C is a top view of the engagement claw 81.

As can be seen from FIG.
The lever 80 can be closed even if is not engaged with the engaging claw 81 or the engagement is incomplete. However, in this state, since the storage lid 68 is not completely closed, outside air enters the storage box 67 and cools the heater 65 and the like, causing heat loss.

To prevent such a situation, FIG.
As shown in (b), the non-engagement prevention member 82 is provided, and when the engagement between the hook 78 and the engagement claw 81 is incomplete, the hook 78 hits the non-engagement prevention member 82 and jumps out. This prevents the storage cover closing prevention cover 76 from closing against the protruding hook 78.

The storage lid closing prevention cover 76 is
Is screwed to the storage cover
Does not close normally, the body case 8 also does not close properly. Therefore, the engagement state between the storage lid 68 and the storage box 67 can be determined based on whether or not the main body case 8 is normally closed.

Although the main body case 8 and the storage lid closing prevention cover 76 are screwed as described above, the main body case 8 and the housing case 8 are connected to each other in order to prevent the heat of the deodorizing section 5 from escaping to the outside air. A heat insulating member 8 between the storage lid
3, a female screw is formed on the connecting member 84 having low thermal conductivity such as ceramics, and the male screw 85 is formed on the female screw from the main body case 8 side and the storage lid closing prevention cover 76 side. And these male screws 85 are prevented from contacting each other.

The ventilation unit 4 includes a fan 86 that draws outside air into the processing tank 9 and then exhausts the air through the deodorizing unit 5 and the double bottom of the processing tank 9, and includes the air sent from the processing tank 9 to the deodorizing unit 5. And a filter 87 for removing dust that is generated.

As shown in FIG. 22, the filter 87 is provided with a mesh net 89 on the bottom surface of a boat-shaped frame 88.
A nonwoven fabric or the like is placed thereon, and a filter handle 59 is provided above the frame body 88. Note that such a filter 87 requires regular maintenance such as cleaning and replacement.

Then, this filter 87 is
Is inserted into a filter insertion opening 90 provided in the main body case 8 at a position corresponding to the depression 44 of the inner lid 40 in FIG.

At this time, a guide 91 is provided in the filter insertion port 90 so that the filter 87 can be mounted smoothly.

As described above, the magnet 45 is provided on the handle 59 of the filter 87, the first switch 46 is provided on the inner cover 40 at a position facing the magnet 45, and the first switch 46 is provided on the body case 8 side. A second switch 47 is provided.

The first switch 46 and the second switch 4
7 is set to "ON" when it receives a magnetic field,
For example, when the closing cover 38 is in an open state, the first switch 46 does not receive the magnetic field of the magnet 45, and thus is “OFF”.
When the closing lid 38 is closed, the first switch 46
Is turned “ON” by receiving the magnetic field of the magnet 45.

When the state in which the first switch 46 is "OFF" and the second switch 47 is "ON" continues for a predetermined time (a time sufficient for putting organic matter such as garbage into the processing tank 9), It is determined that the closing of the input lid 38 has been forgotten, and an alarm is output, thereby preventing the closing of the input lid 38 from being forgotten.

If both the first switch 46 and the second switch 47 remain "OFF" for a predetermined time (for example, the time required for replacing the filter 87), it is determined that the filter 87 is not mounted, and an alarm is issued. Is output, thereby preventing the operation without the filter 87.

Further, when the second switch 47 is kept "ON" for a predetermined time (for example, a period for maintaining the filter 87), it is determined that the maintenance of the filter 87 has been forgotten, and an alarm is output. The filter 87 is prevented from being used for a long time without being cleaned.

These alarms are output by the alarm means based on signals from the first switch 46 and the second switch 47 by means of a sound such as a buzzer or light such as an LED.

Next, the operation of the organic substance processing apparatus having such a configuration will be described, including procedures for sucking in and exhausting outside air. First, the charging lid 38 is opened, and organic matter such as garbage is charged into the processing chamber 11 of the processing tank 9 and the charging lid 38 is closed.

At this time, if the closing lid 38 is forgotten to be closed, the first switch 46 does not receive a magnetic field, so that a warning is given based on the signal from the first switch 46 that the closing lid 38 is open. .

It is necessary to periodically clean or replace the filter 87. If the filter 87 is forgotten to be reattached in such a cleaning operation, the first switch 46 and the second switch 47 are turned off. Since there is no magnetic field, it can be determined that there is no filter 87.
The alarm from the switch 47 outputs an alarm to that effect.

Since the filter 87 must be set during operation of the apparatus, the handle 59 of the filter 87 is covered with the input cover 38. Therefore, there is no risk of inadvertently removing the filter 87.

The charged organic matter is mixed with the processed material in the processing chamber 11 by the stirrer 10 and subjected to a decomposition treatment by the carrier to be processed into powder.

It is to be noted that a large amount of water adheres to the newly charged organic matter, and there is a concern that the organic matter may adhere to the inner wall of the processing tank 9. , Stagnation of organic substances is suppressed. Therefore, the organic matter is not burnt or the microorganisms are not killed.

Thereafter, the processed material is transferred from the processing chamber 11 to the discharge chamber 12 via the transfer port 15 by the movement of the stirring body 10, and waits for discharge.

To remove the processed material, the key 62 of the door cover 54 is unlocked, the door cover 54 is opened, and the discharge door lock 55 is loosened. Then, the handle 52 is turned to open the discharge door 53.

As a result, the processed material in the discharge chamber 12 is
When the swash plate 50 is slid from the discharge port 49 by the movement to zero, the swash plate 50 is discharged to the outside of the machine.

Since the gap formed between the opening on the processing tank 9 side and the opening on the main body case 8 side is closed by the side plates 50a, 50b, 50c and the swash plate 50 constituting the chute 51, the outside air is blocked. There is no intrusion into the apparatus to cool the processing tank 9, the deodorizing section 5, and the like.

When the discharge of the processed material is completed, the handle 52
The discharge door 53 is closed and the discharge door lock 55 is closed.
Then, the door cover 54 is closed.

At this time, if the discharge door 53 is forgotten to be closed or is not completely closed, the handle position regulating rib 64 provided on the door cover 54 hits the handle 56 of the handle 52, so that the door cover 54 is closed and locked. Can not do. Therefore, it is possible to prevent the discharge door 53 from being forgotten to be closed or from being incomplete.

Further, even if external vibration or the like is applied to the apparatus, the position of the handle 52 is regulated by the handle position regulating rib 64, so that the discharge door 53 does not open.

On the other hand, the outside air is drawn into the control unit 92 from the intake port 93 by the exhaust fan 94 provided in the control unit 92, cools the electrical components such as the triac, and is heated and deodorized by the deodorization unit 5. Then, after facing the pipe 110, the air flows into the space in which the fan 86 and the stirring motor 24 are housed, absorbs the heat generated from these, becomes high-temperature air, and flows into the processing tank 9 from the in-machine air intake port 111. I do.

Therefore, heat which is originally discarded is recovered and high-temperature air is supplied to the processing tank 9, so that thermal efficiency can be improved.

In the treatment tank 9, the microorganisms are activated by the oxygen in the supplied air to decompose the organic matter to produce a processed powder. At this time, a gas with a bad smell is generated, so this exhaust gas is led to a heater 65 in the deodorizing section 5 and heated by the heater 65 to enhance the deodorizing action of the deodorizer 66 to deodorize.

The temperature of the exhaust gas deodorized in the deodorizing section 5 is as follows:
Because it is high enough, exhausting as it is will reduce thermal efficiency. On the other hand, the temperature of the processing tank 9 needs to be raised in order to activate the microorganisms and increase the decomposition processing speed.

Then, the high-temperature exhaust gas from the deodorizing section 5 is guided into the double bottom of the processing tank 9, where the processing tank 9 is heated and finally discharged from the chimney 95.

At this time, if a large temperature distribution occurs due to the high-temperature exhaust gas being blown to a part of the bottom of the processing tank 9, there is a possibility that organic matter and the like in the processing tank 9 may be scorched or microorganisms may be killed. Therefore, the air distribution plate 18 and the heat equalizing member 20 are provided on the double bottom so that the exhaust gas uniformly blows to the bottom of the processing tank 9 and the heat spreads quickly throughout. Like that.

In the above description, the case where the filter 87 is manually attached and detached to perform maintenance such as cleaning is described, but the configuration described below may be adopted.

That is, as described above, the filter 87 requires periodic maintenance such as cleaning because dust such as a processed material adheres. If the maintenance is short, such as one week, the maintenance is not performed. The work may also be troublesome.

In such a case, as shown in FIG. 23, it is possible to remove dust adhering to the filter in conjunction with the charging lid 38.

That is, a one-way cam (not shown) that rotates in conjunction with the opening and closing of the loading lid 38 is provided, and a toothed roller 96 that rotates only in one direction is provided, and a belt-shaped filter 97 is provided on the main body case 8 side. Provided filter unit 9
8 is provided.

The filter unit 98 is stretched by two filter rotation shafts 103 facing each other, and a gear roller 99 is fixed to one of the filter rotation shafts 103.

Then, for example, when closing the charging lid 38,
The toothed roller 96 rotates by engaging with the end of the input lid 38, whereby the gear-shaped roller 99 rotates, whereby the filter 97 rotates.

Since the duct connecting portion 100 is in contact with the filter 97, dust adhering to the filter 97 is removed by being scraped off.

As shown in FIG. 24, it is also possible to use a motor 104 for automation. In such a case, the number of rotations of the filter 97 can be set arbitrarily, so that the dust can be sufficiently removed at the duct connection portion 100 and the motor 104 can be rotated forward and backward.

In this case, the operation timing of the motor 104 can be performed simultaneously with the opening / closing operation of the closing cover 38, and the first switch 46 provided on the closing cover 38 as shown in FIG.
If the motor is operated by the signal from the
There is an advantage that there is no need to set the operation timing of No. 4.

Needless to say, even when the filter 97 as shown in FIGS.
The motor 10 needs to be washed or replaced, or the motor 10
In such a case, the unit can be taken out from the take-out lid 105 of the filter unit 98 to perform desired processing.
